That's the way that lpr works under dosemu.  It's my understanding that the objective is to print a whole page at a time because that's how modern printers work.  Since most dos programs don't send a page end/page break, dosemu just waits for a few seconds to see if anything more is coming; if not the page is assumed complete and send it to the printer.
